VENTILATING APPARATUS.

Application filed August 26, 1926. Serial No. 131,608.

This invention is a ventilating screen construction that is translucent but not transparent. In other words, it permits the pas sage of air and sunlight, but not enough light to enable one to see objects through 1t.

The invention is designed for Window screens and ventilating apparatus in hotels, apartment houses, tenement houses, and like places where people need ventilatmg means it. which will not be transparent.

The chief feature of the invention consists in providing a plurality of pairs of obliquely placed screens, one pair-spaced above another so that the lower edge of each oblique screen it of each pair Will be substantially 1n the same plane as the upper edge of the ad aCent pa rs of screens or overlap slightly, and there will be ample space between the two pairs of screens for the passage of air.

in combining with the above a centrallylocated vertically-removable screen made of wire netting, cloth or other reticulated frame or fabric through which air can pass.

lt is thus apparent that such ventilating construction can be used as window screens in residences, hotels, apartment and tenement ltd houses and can also be used for the ventila tion of interior rooms, corridors and the like 30 so as to provide ample ventilation and yet fully protectthe occupants of the room or building from being seen by anybody outside.

The device also screens out insects, files, etc, during the summer and acts as an a r filter durin the winter and efiectually d1- verts rain, a though permitting ventilation.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim:

hi the drawings, Figure l is a front elevation of a window frame with such ventilating screen therein. Fig. 2 is a central vertical section through the same. Fig. 3 is a part of what is shown in Fig. 2 onan enlarged scale. Fig. d is a section on the line fit-4i: of F 1g, 3 through a portion of an angular screen. 1r 1g. 5 is a plan view of a portion of an angular screen. Fig. 6 is a. horizontal sectlon at the top of the screen construction and showing the latter in plan.

There is shown in the drawings a window frame 10 and a ventilating screen mounted therein. The ventilating screen when constructed as shown has a sheet metal plate removably and slidably mounted adJacent till Another feature of the invention consists the side of the window frame. It is vertically slidable thereon by means shown in F ig. 6, Where the screen frame 15 is bent A-shaped at 20 to" enter and slide in a W-shaped vertical guide 21 that is secured to the side of the window frame. The screen frame or plate 15 is made of metal and has two vertical series of tongue plates 14 punched out of the same, as shown in Figs. 3 and 4, to which the ends of the wire or other screens 12 are secured by the rivets 26. These tongues 14 and screens 12 are arranged obliquely to a vertical line, as seen in Fig. 3, and they are arranged in pairs, one pair located above another, as there shown, the two pairs being A-shaped and the lower end of each pair of screens extending on a line with or overlapping the upper end of the next pair of screens below. These screens are herein termed angular screens and are arranged at an angle of about 4.5 degrees from the perpendicular.

The screens can be inserted in windows or walls and be slidable in the windows as described, the particular arrangements for such mounting not being very material to this invention and not being described more fully. The angular screens may be made of any translucent glass or water proof wire screen so that the rain will be deflected and diverted thereby from entering the room even if the window be open and also the screens will be translucent, but they will not be suficiently transparent to enable one from the outside to see an object through the same.

Another feature of the invention consists in combining with the foregoing described screen construction a vertical screen 11 that has a frame 16 which is insertable in and removable from said previously described screen construction. This may be accomplished by providing a guideway 22 in the side frame plate 15 of the angular screen construction heretofore described, as shown in Figs. 3 and 6, although the invention is not limited to this construction for the introduction of the vertical screen. While the vertical screen is shown provided with wire netting 11, which is desirable in the summer time, in the wintertime a cloth screen may be used instead of that shown so that it will filter the air as well as permit the passage of air through it. This vertical screen can be made of any suitable material, Whether cloth or wire netting, according to the imfill mediate need. The screens or shutters 12 are not limited to any particular material, but ma be made of any material desired.

The ottom plate of the frame 15 is provided with a central slot 17 through which the screen 11 and its frame 16 is lnsertable and removable. Said screen and its frame are held in place by the locking lug 18 pivoted to the plate of the frame 15 at 19, so thatit may be moved in and out of locking position. Thus, one type of screen may be readily substituted for another when desired, or removed for an other purpose, such as cleaning or the li re, and replaced.

The invention claimed is:

Ventilating means including a frame having an opening in the lower part thereof, a vertical series of angular screens secured Within said frame arranged in substantially 20 A-shaped pairs, said screens being formed memes of a translucent but non-transparent material for permitting the passage of light while preventing vision therethrough, the pairs of screens being spaced from each other vertically so that the lower edges of each pair of screens will extend down at least to the same plane as the upper edges of the pair of screens below so as to permit the free passage of air while preventing the passage of the elements, a vertical screen insertable in and removably mounted through the opening in said frame between each series of angular screens, and a latch secured to the lower portion of said frame adjacent the opening therein for locking said vertical screen therein.

In Witness whereof, I have hereunto affixed my signature.
